Outline
To analyze theassociation and interactionof night shift work and unhealthy lifestyle on hyperhomocysteinemia(HHcy), and to provide basis for theHHcy preventionamong railway workers.
Total of 6 926 railway workers who received physical examination in a hospital in Guangzhou from September to December 2021 were selected as study objects. Binary logistic was performed to analyze correlation, the restricted cubic spline (RCS) model was used to assess the dose-response relationship, and the interaction of night shift work and unhealthy lifestyle with HHcy were analyzed.
The prevalence rate of HHcy among railway workers was 23.3%. Logistic regression showed that night shift work lasted 0-2.9 years (OR=1.340, 95% CI:1.120-1.603), night shift work frequency ≤ 1 d/w (OR=1.302, 95% CI:1.029-1.646) or ≥ 4 d/w (OR=1.516, 95% CI:1.248-1.841), smoking (OR=1.516, 95% CI:1.248-1.841), overweight (OR=1.173, 95% CI: 1.030-1.335) were positively correlated with HHcy. Sleep duration > 7 h/d and exercise were negatively correlated with HHcy (P<0.05). RCS model found a nonlinear relationship of night shift work with HHcy (Ptotal <0.001,Pnon-linear=0.001). No multiplicative and additive interaction of night shift work and any unhealthylifestyle with HHcy were found(P> 0.05). Among different night shift conditions, smoking, almost inactive, overweight/obesity, and ≤ 7 h/d sleep had a higher risk of HHcy (P<0.05).
Night shift work and unhealthy lifestyle are risk factors for HHcy. In different night shift work conditions, smoking, almost inactive, overweight/obesity, sleep duration ≤ 7 h/d can increase HHcy risk.
